3.7.1 Tilt sensors
The tilt sensor system disables the power from the incoming low voltage source
when a tilt sensor detects a tilt of a cabinet of the EVSE in any direction. The tilt
sensor is generally closed and opens when there is an unacceptable tilt of the
cabinet. For the threshold tilt, refer to section 12.11.
The tilt sensors require a 24 V power supply, daisy chain-connected from the power
cabinets to the charge post. This power supply is not included in the scope of ABB
EV Infrastructure. ABB EV Infrastructure recommends to use an uninterruptible
power supply.
It is possible to install tilt sensors afterwards. Ask ABB EV Infrastructure. Refer to
section 1.12.
Example: An incident such as a heavy duty vehicle that crashes into the charge post
can open the tilt sensor.
